Once again thanks for the detailed response, much appreciated.
I faced with exactly same problems and spent a lot of time to debug it. I'm glad to share my experience and save other people from such nightmares. :)

Additionally I found that pbuf_alloc() call hierarchy contains sys_mbox_***() calls. It may cause non-***FromISR() calls. Even if your lwip configuration exclude them, check whether your port do system calls in LWIP_PLATFORM_DIAG() and LWIP_PLATFORM_ASSERT() which are used in LWIP_DEBUGF() across all the lwip code.
